I would like to join the call as well as I am just starting to study Node Red, having retired only yesterday.
Thus far, set up a Pi4 with Node Red following the WiKi, then followed Dave's YouTube video on the Keyestudio 4 relay board and set this one up to match.
It was a good introduction and was easy to follow along on another screen. Thanks for posting guidance for us to follow!
